Embodiment Construction

[0024] Invention idea of ​​the present invention is:

[0025] The photoelectric theodolite servo system performance test system input contains a sequence of pictures of a target, and the position of the target in each picture has a certain movement law. The location of the object in each image is known. Send the known moving target position to the photoelectric theodolite servo system through the communication interface. The servo system performs correction and tracking according to the deviation between the target miss amount in the field of view and the center of the field of view, and at the same time sends the angle position information of the photoelectric theodolite to the performance testing system through the communication interface. The performance test system records the angle position information and fits the position change of the target in the image according to the angle position change of the photoelectric theodolite, and displays it to the test personnel throu...

Abstract

The invention relates to a device for testing performance of a servo system of an electro-optic theodolite. The device comprises a simulated target generator and a servo system control display, wherein the simulated target generator is used for generating a target movement sequence pictures and determining the target position corresponding to each picture; and the servo system control display is used for enabling the servo system of the electro-optic theodolite to control the electro-optic theodolite to rotate according to the miss distance of the simulated target, recording the rotating angle position of the electro-optic theodolite, and displaying the simulated target movement image of each target image under the rotation of the electro-optic theodolite. According to the device and the method for testing performance of a servo system of an electro-optic theodolite, the tracking performance of the servo system capable of controlling the electro-optic theodolite can be accurately evaluated, the target tracking performance of the servo system can be intuitively displayed by the device based on the movement state of a target in the image, and a real target tracking effect image of the servo system can be simulated.

Description

technical field [0001] The invention relates to the field of detection of rotation performance of a servo system, in particular to a performance test device and a test method of a photoelectric theodolite servo system. Background technique [0002] The photoelectric theodolite is a high-precision spatial position measurement device, which is widely used in sea, land and air weapon test ranges and astronomical observations. It uses laser, infrared, TV, radar and other detectors to obtain the deviation between the moving target in its field of view and the center of the field of view, and then transmits it to the servo tracking system for correction and tracking, so that the theodolite can aim at the target and guide other tracking equipment. [0003] In order to achieve stable target tracking and guidance, the theodolite must have a good servo system and use complex control algorithms to achieve precision requirements. The servo system needs to be developed, matched and debu...
